Abstract

We demonstrate the ability to receive live color analog television and video game signals with the use of the Rydberg atom receiver. The typical signal expected for traditional 480i National Television Standards Committee format video signals requires a bandwidth of over 3 MHz. We determine the beam sizes, powers, and detection method required for the Rydberg atoms to receive this type of signal. The beam size affects the average time the atoms remain in the interaction volume, which is inversely proportional to the bandwidth of the receiver. We find that small beam diameters (less than 100 μm) lead to much faster responses and allow for color reception. We demonstrate the effect of the beam size on bandwidth by receiving a live 480i video stream with the Rydberg atom receiver. The best video reception was achieved with a beam width of 85 μm full-width at half-max.
